Application filed October 22, 1920. Serial No. 418,821.

To all whom it may concern.'

Be it known that I, HERBERT TowNsEND,.

a subject of the King of Great Britain and Ireland, residing at Philadelphia, yin the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Heaters, of which the follow,--

therethrough will be raised in temperature` and cause the walls to be heated so that air passing through only parts of the heater will be raised in temperature and then distributed from the top of said heater.

Another object of the invention is to provide a heater with passageways certain ones of which are formed of pipes, said pipes being spaced apart to provide air passageways therebetween.

A further object of the invention is to conf struct a heater having passageways as above described and including a hood and the covering for catching the products of combustion from the burner from which said products of combustion are conveyed to a chimney by means of a pipe and having a pipe leading from the top of the heater proper for conveying heated fresh air to a room or chamber to be heated. i

A still further object ofthe invention is to provide a double walled partition forming the upper passageways so as to produce a water jacket whereby a circulation of water may be raised in temperature andvdistributed about a building for heatingthe rooms thereof.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specically designated bythe claims.

In order-that those skilled in the art to which this invention appertains, may understand how to make and use the same, I will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this application, in which Fig. l, is a side elevation of a heater em` bodying my improvements, a portion thereof being broken away and shown in section to clearly illustrate the construction.

Fig. 2, is an inner cap of the heater.

Fig. 3 is a side elevation or thereof having a portion brokenv away and shown insect-ion.y i U Fig. 4, is a` section at the lline 4 4 of Fig. l.

Fig. 5, is a View similar to Fig. 1 of a modification showing'the hood applied there to for catching the products of combustion plan view of the. top or edge. View I and -illustrating the pipe passing through said hood `from the top of the heater for distributing heated fresh air.,

Fig. 6, is a plan View partly brokenaway constructed for. use as a hot waterheater.

A and shown in' section illustratingethe heater j Fig. 7, is a side elevation thereof partly broken away and shown in` section; to illustrate the construction. 'l

In carrying outL my invention` as embodied in Figs. 1 to 4 inclusive,2 represents the base of the heater comprising a bottom 3 supported on suitable legs or feet 4 andhav-` ing a side wall l5 forming a burner chamber 6, the upper portion of` which is partially closed by the burner chamb'ertop 7 ,havingl a central opening -8 therethrough. Extending from 4the burner chamber and the top17 surrounding the opening 8 is the stack 49 open at both'ends.,

From the burner chamber top 7 projects a central opening 14 of greater size or diamv eter than the stack 9 so as to be spacedfrom the latter and from .thishead 1l: extends an upwardly projectingfheating drum `15 sur' rounding the opening 14, while its upper end l projects above the stack 9 and is closedbv the drum top 16, thereby forming with the, passageway for air passing through stack 9 a the stack.

On each of the flanges 13 so as to sur-A round the same is mounted a pipe 17 normally open` at ea'ch end and these ypipes are located about the heating drum and spaced' i' therefrom and from each other sov as to form air passageways 18 therebetweenleading to the heating drum.

The upperends of [these pipes are 'held in their positions by .a ring 19 'which maybe a separate piece, and secured `to the pipesl by some suitable fastening means such as rivets, or said ring may be carried by or formed as an integral part of the top or covering having a central portion or plate 21 provided with perforations 22 and having integral radiating arms 23 to cover the upper ends of the pipes 17 and these arms are provided with perforations 24 for the outlet of the heated air which is also the purpose of the perforations 22.

Inthe burner chamber 6 is located a burner 25, the one yhere shown representing an ordinary gas burner but this burner may be of any desirable construction suitably adapted for using oil or other fuel for producing the required heat.

In practice the walls of the heater will be heatedy by the flame from the burner 25 sothat air passing into the burner chamber 6 through the opening 26 in the bottom wall 3 of the base will pass over the flame of the burner and will be raised in temperature as it comes in contact with the different walls of the heater during its passage through the stack 9 then over said stack and downward between the walls thereof and the walls of the heating drum then beneath the head 11 and upward through the different pipes 17 from which it will pass out through the vperforations 24, and at the same time fresh air will flow through the passageways 18 between thedifferent adjacent pipes 17 until it contacts with the heating drum where. the temperature of the air will be raised ,and caused tof flow upward and because of the ring 19 said heated air will pass toward the center of the heater and then out through the perforations 22 in the central portion of the top 20. l

Because of the construction here illustrated' an exceedingly large heating area is provided and because of the circuitous passageways formed it has been found that the air is sufiiciently agitated Vor broken up to cause it to absorb a great amount of heat which is of great advantage in devicesof this character. n

In Fig. 5, Ihave shown'a modified form of-my invention in which a hood 30 'forms the upper outer shell of the heater and surrounds the trunks or conduits but spaced therefrom and this hood is provided with feet or projections 31 at the bottom thereof so as to rest upon the head 11 thereby leaving open spaces for the passage of air into said hood and then between the pipes 17 in its movement toward the heating drum. This hood isclosed at the top except for a hole 32 for a purpose hereinafter described and leading from said hood, near the upper end thereof, is a smoke pipe or flue 33 for conveying the products of combustion, whichpass upward through the trunks, to a chimney or other'suitable outlet.

A ceiling 27 is provided to take the place of the top or cover 2() and is disposed across the interior of the hood above the pipes 17 having openings 50 for the-pipes 17 and a central opening 28 from which leads a pipe 29 for distributing the heated air which passes between the pipes 17 and over the heating drum, said pipe 29 projecting through the hole 32 in the top of the hood. In all other respects the construction is identical to that hereinbefore described.

In Figs. 6 and 7, 34 represents the outer wall or shell of the heater having a burner chamber top 35 disposed across the interior thereof to form the burner chamber 36 in which the burner 37 is located. The burner chamber top is provided with an opening- 38 about which is disposed a stack 39 projecting upwardly from the wall 35.

Surrounding the stack 39 and spaced therefrom is a water jacket 40 which acts similar to the heating drum 15 so as to produce with the stack and the shell `a circuitous air passageway and said shell preferably has a top wall 41 with a hole 42 therethrough for the exit of the air. The water jacket has a water inlet pipe43 leading thereto adjacent its lower end and a watei outlet pipe 44 at its upper end so that water entering the jacket will circulate around the same and be heated by the circulation'of warm air thereto. f

Of kcourse I do not wish to be limited to the exact details olf construction as herein shown as these may be varied within the limits of the `appended-claims without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is1- 1. A heater comprising in combination, abase having a burn-er chamber therein, a stack supported by the base and communi'- cating with the burner chamber, a head also supported by the base, said head having a central opening of greater diameter thanl the stack through which the latter. passes and a plurality of surrounding openings, said head with the top of the burner chamber forming a passageway for air from theI central opening to the other openings aheating drum supported by the head about thel central opening, said drum being closed at its upper end and open at its lower end and partially enclosing the stack with its walls spaced therefrom, pipes also supported by the head and surrounding the other' openings therein, said pipes being so spaced as to permit air to circulate therebetween for passage to the heating drum and a perforated top supported by the pipes for covering their upper ends and t-he space bounded by said pipes. v

2. A heater comprising in combination, a base having a burner chamber therein,r a stack supported by the base and communi` eating with the burner chamber, a head also supported by the base, said head having a central opening of greater` diameter than the stack through which the latter passes andl a plurality of surrounding openings, said head with the top of the burner chamber forming a passageway for air from the central opening to the other openings, a heating drum supported by the head about the central opening, said drum being closed at its upper end and open at its lower end and partially enclosing the stack with its walls spaced therefrom, pipes also supported by the head and surrounding the other openings therein, said pipes being so spaced as to permit air to circulate therebetween for passage to the heating drum, a ring connected with the inner walls of all of said pipes at theirupper ends, a perforated top plate covering the space bounded by said pipes and perforated arms radiating from the top plate and covering the upper ends of said pipes.

3. A heater comprising in combination, a. base having a burner chamber therein, a stack supported by the base and communicating with the burner chamber, a head also supported by the base, said head having a central opening of greater diameter than the stack through which the latter passes and a plurality of surrounding openings,l said head with the top of the burner chamber forming a passageway for air from the central opening to the other openings,
